TADS is a set of programming tools specially designed for writing adventure games. TADS consists of: * A programming language, which resembles C and Java. * A compiler, which reads a set of source files written in the TADS programming language and produces a portable binary game file. * A library, which provides a set of generic adventure game definitions. * An interactive debugger, which lets you examine your program's execution in order to find and fix programming errors. * An interpreter, which a player uses to run your game. See http://www.plover.net/~textfire/raiffaq/ifaq/ for more information about obtaining game files.

fv is an HDRI viewer. Currently supported formats are the followings: * Greg Ward's HDR (also known as Radiance/PIC/RGBE). See http://www.graphics.cornell.edu/~bjw/rgbe.html for details. * Paul Debevec's PFM (Portable Float Map). See http://netpbm.sourceforge.net/doc/pfm.html for details. fv reads data from the standard input or files specified as arguments. In the latter case, each file may be compressed one with gzip or bzip2. The file may also change after fv is invoked, except its header part. fv checks whether the file changes and updates the display if necessary. This feature is useful for checking intermediate outputs from renderers.

This is a simple sendmail milter which adds an X-RBL-Warning header to any emails that are received that come from an open relay as determined by your choice of RBL checking service (i.e. bl.spamcop.net). This is useful if you'd rather have the mail user agent (MUA) deal with potential spam rather than just blocking it in case you loose legitimate messages. Note that the X-RBL-Warning header is only set if the site was found to be an open-relay.

This program is for any user who retrieves ftp files via ftpmail or bitftp servers. It runs quietly in the background and watches the user's mail directory. When the mail- retrieved file has arrived in full, rftp puts the pieces together in order and stores the tarball in a directory. I wrote this several years ago when my only link to the Arpanet was a uucp link. These days, most FreeBSD users have a direct link to the net. For the dozens or hundreds who don't this should be of use.

IOG is a network I/O byte grapher made to graph cumulative KB/MB/GB totals for hours/days and months. It is intended to be simple, fast (support thousands of hosts) and integrate well with MRTG. Data for each host is updated hourly and HTML graphs are created. It uses a data consolidation algorithm which allows for a small, non-growing database file for each host. No external graphing libs or executables are required. IOG has been used in several production ISP environments, including at the authors company, Dynamic Internet (dyni.net). -Larry Rosenman <ler@lerctr.org>

AI4R is a collection of ruby algorithms implementations, covering several Artificial intelligence fields. It implements: * Genetic algorithms * Self-organized maps (SOM) * Neural Networks - Multilayer perceptron with Backpropagation learning - Hopfield net * Automatic classifiers (Machine Learning) - ID3 (Decision Trees) - PRISM (J. Cendrowska, 1987) - Multilayer Perceptron - OneR (AKA One Attribute Rule, 1R) - ZeroR - Hyperpipes - Naive Bayes - IB1 (D. Aha, D. Kibler - 1991) * Data clustering - K-means, Bisecting K-means - Single linkage, Complete linkage, Average linkage, Weighted Average linkage, Centroid linkage, Median linkage, Ward's method linkage - Diana (Divisive Analysis)

KeePass is a free open source password manager, which helps you to manage your passwords in a secure way. You can put all your passwords in one database, which is locked with one master key or a key file. So you only have to remember one single master password or select the key file to unlock the whole database. The databases are encrypted using the best and most secure encryption algorithms currently known (AES and Twofish). This is the official KeePass application, which was originally only available for Windows, but has now been re-written with .Net and able to be run on BSD, Linux and Mac OS X with Mono.

This code appears to have only cursory resemblance to Bruce Schneier's blowfish and twofish algorithms in that it too has a table-based decoder. Derivation from FairKeys code by Jon Lech Johanson at nanocrew.net. If you don't know what that is, don't bother looking here further. This is a Pure Perl implementation. I doubt there is any need for xs coding for what would mainly be processing 16 bytes at a time. This code is part of an ongoing effort to clone portions of the Apple iTMS in Perl for portability. See www.hymn-project.org for prior efforts by others.

FVCool is the FreeBSD version of the famous VCool software (http://vcool.occludo.net) which changes the PCI configuration data of some chipsets and thus allows AMD Athlon/Duron CPUs to go into power-save mode. This makes the CPU consume a lot less electric energy, and it produces a lot less heat as well. This trick is not a secret - on FreeBSD, you can actually achieve the same effect which this software has using the "pciconf" command. Please note that this software may have a negative impact on the system's stability and thus should not be employed in production or mission-critical environments.

"Swapd" is a daemon that watches free memory and manages swap files. If free memory drops too low, additional swap files are created. Additionally, if there is too much free memory, swap files are deactivated and disk space may be reclaimed. "Linux swapd" (http://sourceforge.net/projects/swapd/) didn't work very well, but the idea was good. I started making a version that would work and would also be somewhat portable. It currently compiles on Linux and FreeBSD, but requires `libstatgrab' (http://www.i-scream.org/libstatgrab/) to work on platforms that don't have /proc/meminfo (i.e., platforms that aren't Linux).
